9.5" Height Modular Weathering Steel Planter Panels

Clean lines, low profile, built to last. Straightcurve's 9.5" weathering steel modular panels are the go-to choice for landscape edging, shallow raised beds, patio borders, and rooftop installations where a sleek, low-profile look is the goal — without sacrificing contractor-grade durability.

We offer three heights to suit any application:

• 15.75" Height — Mid-height option, great for accessible gardening and tiered designs
• 22" Height — The most popular height for deep raised garden beds and statement planters

• 2mm thick CorTen (weathering steel) — built to outlast the job site
• Folded lip top edge — no sharp edges, clean professional finish
• 6 panel lengths from 15.75" to 78.75" — mix and match any configuration
• Modular connectors for square, rectangular, L-shaped, and custom layouts
• Arrives in pre-rust black/gray — natural patina develops after installation
• 1.8" top lip thickness for a bold, finished look

• Landscape edging and garden borders
• Shallow raised beds and planter boxes
• Patio and hard surface installations
• Rooftop gardens and green roofs
• Retaining walls (single wall or closed shape)
• Long garden barrier beds

Every planter starts with a plan. Use our Planter Box Configurator to map out your design, choose your panel sizes, and generate a complete parts list — so you order exactly what you need, nothing more.

Closed Corner — For traditional square or rectangular planters. Connects panels at 90° for a clean, enclosed shape.

Open Corner — For L-shaped planters. Allows panels to connect at an outward angle for custom layouts.

Straight Join — Connects two panels end-to-end to extend the width or height of your planter.

• Brace any time you use a straight join to create a longer run — 1 brace per panel.
• The 78.75" panel always requires bracing — 2 per panel recommended.
• Option 1: Anchor Post & Bracket Kit — Use anywhere on the panel that needs support.
• Option 2: Universal Bracing — Hooks onto straight joins. Not suitable for mid-panel bracing on the 78.75" panel; use the anchor post kit instead.
